To all whom it may concern.-

Be it known that I, RrrcHIE E. TEETs, a

citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented a new and useful Improvement in Cement-Block-Molding Machines, of which the following is a specifica- 'tion.

My invention relates to a cement-blockmolding machine, and has for its object to provide a simple, convenient, and efficient machine of the kind whereby various forms ofbuildin thickness this object by constructing a molding-machine, as hereinafter described, and illustrated tions of the connections of the tam ing-plate Fig. 12 is a top provided with frame with its operating-shaft.

box having the side plates 1 and end plates 2 and'the side angle-bars 3. The mold-box is mounted on the legs 4, which are formed of angle -'bars and are suitably secured to the corners of the box.

The legs 4 are cross-connected and braced by side angle-bars 5 and the end angle-bars 6, suitably secured to the legs' parallel with the sides and ends of the mold-box, the side bars 5 .being relatively higher than the end bars 6. the legs 4 the ends 2 of the box and the end brace-bars 6 are connected by channel guidebars 7 with the channel-grooves facing inward. The side angle-bars 3 are secured to the side plates 1 of the box flush with their lower outer edges and with one web of each angle-bar extendin outwardly, and these horizontal webs of t e side angle-bars 3 are crossconnected by the bottom bars 8, seamed thereto by the bolts 9. Upon the bottom bars 8 is supported the movable bottom frame 10,-the side and end members of which are respectively parallel with the sides and end of the box and at equal distances therefrom. To the four corners of the bottom frame 10 are secured the angled upper end portions of the supporting-arms 1 1, which conver e in end pairs at equal angles and have angled lower end portions secured by common bolts 12 to a squai ed lifting-bar 13, the ends of which extend into the grooves of the channel guide-bars 7 and are movable upward and downward therein.

To the under 'side of the end angle-bars 6, slightl out of the longitudinal centers of their engths, there are secured the shaftbearings 14, inwhich are journaled the hollow shaft 15, one end portion of which extends beyond the outer face of its bearing, upon which end portion is mounted the clutch rock-plate 16, and between the bearings at points near the bearings are mounted on the shaft the rock-arms 1 7, the free ends of which are pivotally connected by the connectingrods 18 to the lifting-bar 13, w'hereb when the shaft 15 is rocked'back and fort 1 in 'its bearings by the clutehplate 16 the rockarms 17 move the bottom. frame 10 upward and downward through the mold-box. The connecting-rods '18 are each formed of two sections, which are coupled together b the coupling-sleeve 19, right and left threa ed to engage complementary threaded portions of the sections, whereby the len ths of the con necting-rodsmay be adjusted to increase or decrease the upward movement of the bottom Central between I Io , 1S fixedlymounted, is provided with a short crank-arm extension 33, hav ng a squared v '28 and at right angles thereto.

and a partition or sliown'in 13.

To thtamping-frame bars detachably secured by bracket clamps 59 a tamp-- is placed on the guides, as

ing plate or plates complementary to the mounted on the bottom secured to one end of each bracket by a screw-bolt 62, and the free end of the latch is adapted to swing over a bar 28 and under a lip 63 of the bracket, in which position. it may be clamped on the bar 28 by the screw-bolt 62 and may be readily released therefrom for detachment of the plate by a reverse operation. 4 i

The chimney-block molds l7 and 48 are re spectively provided with the central fluecones 64; and 6-1; and with the air-duct cores 65, by which the blocks molded therein are provided with central smoke-flue and surrounding air-duct sections. The bottom plates 49 and 50 may be provided on their upper faces with depressions adapted to simulate a rock-face finish to the outer faces of the blocks molded thereby.

To adapt the machine to produce blocks of a desired thickness less than the depth of the mold-box, l have provided the plates 66, the upper edges of which are stepped at uniform intervals, preferably of one-inch hei 'ht, and which are mounted on and movable along the end anglednars l} beneath. the lift-bar 1.3. The plates 66 are adjustably secured in. vertical position by stud screw-bolts 6?, secured to the channel. guide-bars 7 and projecting inward through slots 68 in the stepped plates,

the slots extending parallel with the bars 6. These plates form stop-supports for th.e1hft;

bar and limit its downward movement, there by arresting the bottomframe atany d sired step interval above its nermal posit-ion at the bottom of the mold-bo1r towhich the stop-- plates are adjusted.

The bottom and tainping frames having been respectively provided with complemem tery bottom and top plates and the moldbox with suitable partitions therefor (if required) and the plate 66, being adjusted for the desired thickness, the moldbox, from which the tamping-frainc has been removed, shown in Fig. 1, is lilled with a properly moistened mixture of sand and cement and struck off level with the top edge of the box. The operating-lever is then engaged with the rock-plate of the shaft 20in the manner described and the tamping frame is raised thereby a sufhcient distance for the tampingplates to be swung over the top of the moldbox until the triangular stop-guides 69, se-.

cured to the-forwar branch of the bifurcated arms of the tamping-frame, engage suitable bracket-stops 70, secured to the ends of the mold-box, the latter being placed so as to bring the camping-plates in position to enter the mold-boxf The operating-lever is then moved in the opposite direction until the tampingframe is drawn downward and compressed on the contents of the mold-box with the desired amount of pressure. The tamp- -ing-frame is then again raised and swung to one sideof the mold-box, after which the operating lever is disengaged from the rock-plate 2]. and engaged with the rock plate-16 of the shaft 15 and moved to raise the bottom frame through the mold-box until the bottom plates are above the level of the top of the mold-boX, in which position the molded block may be lifted therefrom by the bottom plate on which it rests and carried thereon to a place of storage, where it remains on theplate until it is sufficiently hardened to be handled, the machine being supplied with a number of bottom plates to permit of its continuous operation for the period required for such hardening. When the machine is used for molding solid blocks, the partitions are carried up with the blocks through the mold-box by the bottom frame, where they are readily removed from be tween the discharged blocks and replaced in the guides for the next operation of molding. When the machine is used for molding-chi1nney-blocks, the molded blocks are in like manner lifted from the machine and carried away on the bottom plate to a place ofdeposit and tnere inverted on a suitable support for the block, after which the mold-plate may be lifted therefrom, thereby withdrawing the cores from the block, whereby ohly a few du plicate molds are required for the continuous operation of molding such blocks.

it will thus beseen that l have produced a molding-machine that is convenient and efficient and readily adapted for molding cement'blocks of various forms and sizes in the same mold-box, thereby making it'unneces sary to provide mold boxes 17 of different sizes suitable for each form and dimension of bloclr. used in the construction of the walls of a buildin What l claim to be new is L In cement-block-molding machine,
